Though Stellar's title track "Archangels of the Sephiroth" and their mini-album 'Stellar into the World' were released on June 27, it seems there are issues with their physical albums over 2 weeks later. The girl group raised funding for their album through Makestar, bringing in 1,132.42% over their goal of $8,322 from December 26 of 2016 to April 24 of this year.

Seeing the physical albums still on "pre-order" status on music sites, member Gayoung expressed her dissatisfaction on Twitter. On July 13, she complained in a now-deleted tweet, "It's been 3 weeks since our comeback. Why do I have to worry about each and every thing when it comes to album production? I want to focus on the stage."

In response, Hyoeun commented, "I can't even laugh now," and Minhee also replied, "Every day is a war. Hoo." Both responses have also been deleted.
